Whenever we link a tribute from a NetCommunity Donation in the connector to a tribute in RE, it always creates a duplicate tribute in the same record with incomplete information, and links to the incomplete tribute. So, I have to write down every donor & tribute ack info, delete the tributes it creates, and reconnect the tributes once I get the gifts into the batch.
You have to make sure that you are on the most recent version of both the site and the plug in. This was fixed at some point.
